Abstract

A key element in any system based on several interconnected computing and/or storage nodes is the interconnection network. Currently, one of the main concerns of high-speed interconnection network designers is how to improve network performance while using the minimum number of network resources. In that sense, in this paper we describe an efficient switch architecture suitable for any interconnect technology implementing deterministic source-based routing. This switch architecture uses the same network resources to provide two issues that improve network performance: Congestion Management and QoS support. We also present results to compare the effectiveness of this architecture to those of other proposals typically used to provide these issues in this context. These results have been obtained for synthetic traffic and for traces from parallel benchmarks and video frames. From the results, we can conclude that in any traffic scenario, our proposal is as effective as the previous ones, while requiring fewer resources and thus being much more cost-effective.
